Bearing-in-Bearing Fidget Spinner Taken to the Max

Posted on July 13, 2017 by John Baichtal

People who know about bearings go through a phase of bemusement with regards to fidget spinners. We say something like, “man, I got a whole box of bearings in the basement.” Then we go through a “OK, I’ll make one” phase and print one out of PLA.

[fishpepper] took that sentiment a step further. After being forced to print spinners for his kids, he got jealous and decided to make his own—but his spinner would be a version for engineers. [fishpepper]’s ginormous spinner consists of five bearings superglued inside each other, with the grease cleaned out of the insides to …read more

Fidget Spinner Gigantor

Posted on July 3, 2017 by Michael Uttmark

Had enough of fidget spinners yet? If you haven’t heard, a toy that consists of a bearing in the center of a multi-lobed flat structure that’s designed to spin around the bearing’s axis with little force has taken the world by storm. Usually, these devices are about 10cm in diameter or less. But, everything is bigger in Texas. So, naturally, students from the University of Texas at Dallas got to work making the largest fidget spinner in the world.

Clocking in at 150 pounds and 45 inches in diameter, this thing is undeniably huge. The structure is made out of …read more

Hackaday Links: July 2, 2017

Posted on July 2, 2017 by Brian Benchoff

A few months ago, we had a Hack Chat with Chip Gracey, the guy behind Parallax, the Basic Stamp, the Propeller, and the upcoming Propeller II. Now we’ve finally got around to editing that transcript. There’s a lot of awesome stuff in here, from learning a Hardware Design Language to the actual costs of fabbing silicon.

Rigol, the manufacturers of every hackerspace’s favorite oscilloscope, announced a new chipset. The current lineup of Rigol scopes top out at around 1GHz. In a prototype scope based on this chipset, Rigol demonstrated 4GHz bandwidth and 20GS/s with one Billion point memory depth. What …read more

Three Magnets Make Fidget Spinners Amazing And Only Engineers Will Appreciate This Hack!

Posted on June 29, 2017 by Brian Benchoff

The fidget spinner posts will continue until morale improves. This time, we’re looking at [TannerTech]’s electromagnetic accelerator for a fidget spinner. [Tanner] can spin his fidget spinner electronically using parts he had sitting around and a clever application of magnets and relays! Engineers hate him!

[Tanner]’s build consists of three magnets mounted on the tip of a fidget spinner’s arms, with the North pole facing outwards. The ‘drive circuit’ consists of an electromagnet — an inductor [Tanner] found in an old TV set — a reed switch, and a MOSFET. When the circuit is placed next to the fidget spinner, …read more

Fidget-Spinning Robot Out-Uselesses Other Useless Machines

Posted on June 26, 2017 by John Baichtal

When the [Director of Legal Evil] at Louisville’s LVL1 Hackerspace decided to demonstrate the uselessness of a 3D printer by printing a fidget spinner, another member at the space’s Tuesday meeting rose to the challenge and built a machine that whose sole purpose is to spin fidget spinners.

[Gary Flispart] used an Arduino clone and what appears to be a motor driver in conjunction with a stepper motor. The motor moves a belt that turns a series of metal scraps serving as a four-bar linkage. The linkage moves the dowel that turns the spinner and then gets out of the …read more

Teaching STEAM With Fidget Spinners

Posted on June 23, 2017 by Brian Benchoff

A huge focus of the maker revolution has been a focus on STEAM education, or rather an education in science, technology, engineering, art, and mathematics. We’ve seen innumerable kits and tools designed to introduce children to STEAM apps, ranging from electronic Lego blocks to robotics kits built around interlocking plastic bricks. These are just a passing fad, but finally, we have what looks like a winner: a STEAM education fidget spinner.

Fidget spinners have spun into our hearts like a shuriken over the last few months, and [MakerStorage]’s latest project taps into the popularity of fidget spinners to put an …read more

Hackaday Prize Entry: Internet of Fidget Spinners

Posted on June 13, 2017 by Brian Benchoff

We just closed out the Internet of Useful Things round of the Hackaday Prize, which means we’re neck deep in judging projects to move onto the final round this fall. Last week, everyone on Hackaday.io was busy getting their four project logs and illustrations ready for the last call in this round of the Hackaday Prize. These projects are the best of what the Internet of Things has to offer because this is the Internet of Useful things.

We’re not sure how [Matthias]’ project will rank. It’s an Internet of Things fidget spinner. Yeah, we know, but there are some …read more

Big Slew Bearings Can Be 3D Printed

Posted on June 12, 2017 by Dan Maloney

Consider the humble ball bearing. Ubiquitous, useful, and presently annoying teachers the world over in the form of fidget spinners. One thing ball bearings aren’t is easily 3D printed. It’s hard to print a good sphere, but that doesn’t mean you can’t print your own slew bearings for fun and profit.

As [Christoph Laimer] explains, slew bearings consist of a series of cylindrical rollers alternately arranged at 90° angles around an inner and outer race, and are therefore more approachable to 3D printing. Slew bearings often find application in large, slowly rotating applications like crane platforms or the bearings between …read more

You Won’t Believe That Fidget Spinners Are Obvious Clickbait!

Posted on June 6, 2017 by Brian Benchoff

I don’t know why fidget spinners are only getting popular now. They’ve been selling like hotcakes on Tindie for a year now, and I’ve been seeing 3D printed versions around the Internet for almost as long. Nevertheless, fidget spinners — otherwise known as a device to turn a skateboard bearing into a toy — have become unbelievably popular in the last month or so. Whatever; I’m sure someone thinks my complete collection of Apollo 13 Pogs from Carl’s Jr. with modular Saturn V Pog carry case and aluminum slammer embossed with the real Apollo 13 mission patch is stupid …read more
